Description

Technical Field

[0001] This utility model relates to the field of workbench technology, specifically to a laser cutting workbench for metal processing. Background Technology

[0002] In the field of metal processing, the laser cutting worktable is a key piece of equipment that carries the workpiece, and its performance directly affects the processing quality and efficiency.

[0003] Based on the above, the inventors have discovered the following problems: Currently, most laser cutting tables for metal processing use serrated plates with fixed spacing as the support structure. This design aims to reduce the contact area between the workpiece and the table surface and reduce the thermal deformation generated during the cutting process. However, when facing metal workpieces with dimensions smaller than the serrated plate spacing, the serrated plates cannot effectively support small workpieces, causing the parts to shake during cutting, which in turn affects the cutting accuracy.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a laser cutting worktable for metal processing, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a laser cutting worktable for metal processing, so as to solve the problem mentioned in the background art that when a laser cutting worktable for metal processing uses a serrated plate with a fixed spacing as a support structure, the serrated plate cannot effectively support the small-sized workpiece when facing a metal workpiece with a size smaller than the gap between the serrated plates.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A laser cutting worktable for metal processing includes a support mechanism and an adjustment mechanism. The support mechanism includes a base, with protective covers fitted on both sides of the upper end of the base. The adjustment mechanism includes a pair of mounting brackets, each set inside the protective covers, with the bottom ends of the mounting brackets connected to the upper surfaces of the base. A pair of sliding rods are fixedly mounted on both sides of the inner interior of each mounting bracket. Several moving blocks are slidably fitted between each pair of sliding rods. A serrated plate is fixedly mounted between the moving blocks on both sides. Rollers are rotatably connected inside each mounting bracket. Several arc-shaped guide grooves are symmetrically formed on the outer surface of each roller. A slider is mounted at the top of each moving block, and the slider is slidably connected to its corresponding arc-shaped guide groove.

[0007] Furthermore, the upper end of the base is provided with a reserved groove on the bottom side of the pair of mounting brackets, and the bottom end of the reserved groove inside the base is rotatably connected to a first gear.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the reserved slot provides installation space for the first gear, enabling it to rotate stably inside the base and ensuring the stable operation of the adjustment mechanism.

[0009] Furthermore, one end of each roller extends through the mounting frame to the outside and is fitted with a second gear, which meshes with the first gear.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the second gear meshes with the first gear, transmitting the rotational power of the first gear to the roller, thereby achieving synchronous rotation of the roller. Through the transmission between the second gear and the first gear, the power transmission is ensured to be accurate and stable, avoiding slippage and ensuring the consistency and reliability of the sawtooth plate adjustment action.

[0011] Furthermore, a pair of retainers are fixedly installed at the bottom of the base, and a connecting shaft is rotatably inserted at the center of each retainer. A worm gear is sleeved on the opposite ends of each pair of connecting shafts.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the cage provides stable support for the connecting shaft, ensuring that the axis position is fixed when the worm rotates, and avoiding failure of the worm wheel and worm to mesh due to shaking.

[0013] Furthermore, a worm gear is fitted onto one end of each of the first gears, and the worm gear meshes with the worm.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the meshing transmission of the worm gear and worm achieves speed reduction and torque increase, transforming the high-speed rotation of the connecting shaft into the low-speed stable rotation of the first gear, while changing the transmission direction, so that the power is effectively transmitted to the roller, meeting the torque and speed requirements required for the adjustment of the sawtooth plate.

[0015] Furthermore, a dual-axis motor is fixedly installed at the bottom of the base between a pair of retainers, and the output ends of the dual-axis motor are respectively connected to the opposing ends of a pair of connecting shafts.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the dual-axis motor drives the connecting shafts on both sides to rotate simultaneously through a pair of connecting shafts, ensuring that the rollers on both sides rotate synchronously, so that the toothed plate can be smoothly adjusted in terms of spacing.

[0017] Furthermore, it also includes a cutting mechanism, which includes a pair of first linear motors, which are respectively disposed on both sides of the upper end of the base.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the first linear motor enables the laser cutting machine to move laterally on the base, which facilitates the adjustment of the cutting start position, adapts to the processing needs of metal sheets of different sizes, and improves the flexibility of the cutting operation.

[0019] Furthermore, a second linear motor is fixedly installed on the moving end of each of the first linear motors, and a third linear motor is fixedly installed between the moving ends of a pair of second linear motors. A laser cutting machine is fixedly installed on the moving end of the third linear motor.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the second linear motor, the third linear motor and the first linear motor work together to control the movement of the laser cutting machine in the longitudinal and vertical directions, respectively, so that the laser cutting machine can accurately position any position of the metal sheet to complete the cutting process.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: The protective cover of the support mechanism of this laser cutting worktable for metal processing protects the internal adjustment mechanism; in the adjustment mechanism, a dual-axis motor drives the connecting shaft to rotate, and through the transmission of worm gear and worm, first gear and second gear, drives the roller to rotate. The arc-shaped guide groove on the roller causes the moving block to slide along the slide rod through the slider, thereby driving the saw blade to move. The spacing of several saw blades can be adjusted so that they can be unfolded when processing large workpieces, and the spacing of the saw blades can be reduced when processing small workpieces to facilitate the support of the workpiece. The first linear motor realizes the lateral movement of the laser cutting machine on the base, which facilitates the adjustment of the cutting start position and adapts to the processing needs of metal plates of different sizes, improving the flexibility of the cutting operation. The second linear motor and the third linear motor work together with the first linear motor to control the movement of the laser cutting machine in the longitudinal and vertical directions, respectively, so that the laser cutting machine can accurately position any position of the metal plate to complete the cutting process.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution: a laser cutting worktable for metal processing, including a support mechanism 1 and an adjustment mechanism 2. The support mechanism 1 includes a base 101, with protective covers 102 fitted on both sides of the upper end of the base 101. The adjustment mechanism 2 includes a pair of mounting brackets 201, which are respectively disposed inside the pair of protective covers 102. The bottom ends of the pair of mounting brackets 201 are respectively connected to the upper end face of the base 101. A pair of sliding rods 205 are fixedly installed on both sides of the interior of the pair of mounting brackets 201. Several moving blocks 206 are slidably fitted between each pair of sliding rods 205. A serrated plate 202 is fixedly installed between the moving blocks 206 on both sides. Rollers 203 are rotatably connected inside the mounting brackets 201. Several arc-shaped guide grooves 204 are symmetrically opened on the outer side of the rollers 203. Each of the moving blocks 206 has a slider 207 installed at its internal top. The slider 207 is slidably connected to its corresponding arc-shaped guide rail groove 204. The protective cover 102 of the support mechanism 1 protects the internal adjustment mechanism 2. In the adjustment mechanism 2, the dual-axis motor 108 drives the connecting shaft 109 to rotate. Through the transmission of the worm gear 105 and worm 106, and the first gear 104 and the second gear 208, the roller 203 is rotated. The arc-shaped guide rail groove 204 on the roller 203 causes the moving block 206 to slide along the slide bar 205 through the slider 207, thereby driving the sawtooth plate 202 to move. The spacing of the sawtooth plates 202 is adjusted so that they can be unfolded when processing large workpieces, and the spacing of the sawtooth plates 202 is reduced when processing small workpieces, so as to facilitate the support of the workpiece.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 The upper end of the base 101 is provided with a reserved groove 103 on the bottom side of a pair of mounting brackets 201. The bottom end of the reserved groove 103 inside the base 101 is rotatably connected to a first gear 104. One end of each roller 203 extends through the mounting bracket 201 to the outside and is fitted with a second gear 208. The second gear 208 meshes with the first gear 104. A pair of retainers 107 are fixedly installed at the bottom inside the base 101. A connecting shaft 10 is rotatably inserted into the center of each retainer 107. 9. Worms 106 are fitted onto the opposite ends of a pair of connecting shafts 109. Worm wheels 105 are fitted onto one end of each first gear 104. The worm wheels 105 mesh with the worms 106. A dual-axis motor 108 is fixedly installed at the bottom interior of the base 101 between a pair of retainers 107. The output ends of the dual-axis motor 108 are respectively connected to the opposite ends of the pair of connecting shafts 109. A pre-reserved slot 103 provides installation space for the first gear 104, allowing it to rotate stably inside the base 101, ensuring the stability of the adjustment mechanism. For stable operation of the 202, the second gear 208 meshes with the first gear 104, transmitting the rotational power of the first gear 104 to the roller 203, achieving synchronous rotation of the roller 203. Through the transmission between the second gear 208 and the first gear 104, precise and stable power transmission is ensured, preventing slippage and guaranteeing the consistency and reliability of the sawtooth plate 202's adjustment action. The retainer 107 provides stable support for the connecting shaft 109, ensuring that the axial position of the worm gear 106 is fixed when it rotates, preventing the worm wheel 105 from swaying due to vibration. When the worm gear 106 fails to engage, the meshing transmission between the worm wheel 105 and the worm 106 achieves speed reduction and torque increase, converting the high-speed rotation of the connecting shaft 109 into the low-speed stable rotation of the first gear 104. At the same time, the transmission direction is changed, so that the power is effectively transmitted to the roller 203, meeting the torque and speed requirements for the adjustment of the sawtooth plate 202. The dual-axis motor 108 drives the connecting shafts 109 on both sides to rotate simultaneously through a pair of connecting shafts 109, ensuring that the rollers 203 on both sides rotate synchronously, so that the sawtooth plate 202 can be smoothly adjusted in terms of spacing.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-4 The system also includes a cutting mechanism 3, which comprises a pair of first linear motors 301. The pair of first linear motors 301 are respectively disposed on both sides of the upper end of the base 101. A second linear motor 302 is fixedly installed on the moving end of each of the first linear motors 301. A third linear motor 303 is fixedly installed between the moving ends of the pair of second linear motors 302. A laser cutting machine 304 is fixedly installed on the moving end of the third linear motor 303. The first linear motors 301 enable the laser cutting machine 304 to move laterally on the base 101, which facilitates the adjustment of the cutting starting position, adapts to the processing needs of metal plates of different sizes, and improves the flexibility of the cutting operation. The second linear motors 302 and the third linear motor 303 work together with the first linear motors 301 to control the movement of the laser cutting machine 304 in the longitudinal and vertical directions, respectively, so that the laser cutting machine 304 can accurately position itself at any position on the metal plate to complete the cutting process.

[0030] Specifically, the working principle of this laser cutting worktable for metal processing is as follows: During use, the dual-axis motor 108 starts, driving the worm gears 106 at both ends to rotate via the connecting shaft 109. The worm gears 106 mesh with the worm wheel 105, transmitting power to the first gear 104. The first gear 104 then meshes with the second gear 208, driving the roller 203 to rotate. The arc-shaped guide groove 204 on the outer side of the roller 203 drives the moving block 206 to slide on the slide rod 205 via the slider 207, thereby moving the serrated plate 202. The movement is adjusted according to the workpiece volume. The spacing is adjusted so that the serrated plate 202 is unfolded when processing large workpieces and the spacing is reduced when processing small workpieces to stabilize the support. In the cutting mechanism 3, the first linear motor 301 drives the laser cutting machine 304 to move laterally on the base 101, the second linear motor 302 controls the vertical movement, and the third linear motor 303 realizes the longitudinal movement. The three work together to position the laser cutting machine 304 at any position on the metal sheet to complete the cutting operation. The protective cover 102 of the support mechanism 1 protects the adjustment mechanism 2 throughout the process to prevent metal scrap from affecting the operation of the equipment.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
